■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the accelerator
pedal while starting the engine under any circumstances.
Doing so may cause an accident resu
lting in death or serious injury.
■Caution while driving
If engine failure occurs while the vehicle is moving, do not lock or open the doors until
the vehicle reaches a safe and complete stop. Activation of the steering lock in this cir-
cumstance may lead to an accident, resulting in death or serious injury.
■Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, press and hold
the engine switch for more than 2 seconds, or press it briefly 3 times or more in succes-
sion. ( →P. 4 7 5 )
However, do not touch the engine switch while driving except in an emergency. Turning
the engine off while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. Th is will make it more difficult to steer and
brake, so you should pull over and stop the vehicle as soon as it is safe to do so.
NOTICE
■To prevent battery discharge
●Do not leave the engine switch in ACCESSORY or IGNITION ON mode for long
periods of time without the engine running.
●If “POWER ON” is displayed on the multi- information display, the engine switch is
not off. Exit the vehicle after turning the engine switch off.
●Do not stop the engine when the shift lever is in a position other than P. If the engine is
stopped in another shift lever position, the engine switch will not be turned off but
instead be turned to ACCESSORY mode. If the vehicle is left in ACCESSORY
mode, battery discharge may occur.
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have your vehicle checked
by your Lexus dealer immediately.
■Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual, such as the
switch sticking slightly, there may be a malf unction. Contact your Lexus dealer immedi-
ately.

■If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may be a prob-
lem with the shift lock system. Have the vehicle inspected by your Lexus dealer immedi-
ately.
The following steps may be used as an emergency measure to ensure that the shift lever
can be shifted.
Releasing the shift lock:
Set the parking brake. (→ P. 1 6 4 )
Turn the engine switch to off.
Depress the brake pedal.
■AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to driver performance and
driving conditions.
AI-SHIFT automatically operates when the shift lever is in D. (Shifting the shift lever to S
cancels the function.) Pry the cover up with a flathead screwdriver
or equivalent tool.
To prevent damage to the cover, cover the tip
of the screwdriver with a rag.
Press the shift lock override button.
The shift lever can be shifted while the button
is pressed.

e vehicle to spin or skid, resulting in an
accident.
■To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking brake and
depress the brake pedal.
If the accelerator pedal is accidentally depress instead of the brake pedal when the shift
lock override button is pressed and the shift lever is shifted out of P, the vehicle may
suddenly start, possibly leading to an accid ent resulting in death or serious injury.

Driving
■The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to AUTO position while the engine switch is in IGNITION
ON mode, the wipers will operate once to show that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the wipers
will operate once to indicate that th e sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F

wipers in any mode other than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is ad opted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun intermittently strikes the
windshield, or if bugs etc. are present on the
windshield.
WA R N I N G
■Caution regarding the use of windshield wi pers in AUTO mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in AUTO mo de. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,

Winter driving tips
●Use fluids that are appropriate to the prevailing outside temperatures.
•Engine oil
• Engine coolant
•Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the front tires.
Ensure that all tires are the specified size and brand, and that chains match the size of
the tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield.
●Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the vehicle
ahead, and drive at a reduced speed suitable to road conditions.
Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
